Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 50/79,55/66,42/52
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 50,55,42
Greatest Common Factor of Numerators i.e. GCF of 50,55,42 is 1 .
LCM of Denominators means LCM of 79,66,52 as per the given fractions.
LCM of 79,66,52 is 135564 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 50,55,42
∴ So GCF of numbers is 1 because of no common factors present between them.
Factors of 50
List of positive integer factors of 50 that divides 50 without a remainder.
1,2,5,10,25,50
Factors of 55
List of positive integer factors of 55 that divides 55 without a remainder.
1,5,11,55
Factors of 42
List of positive integer factors of 42 that divides 42 without a remainder.
1,2,3,6,7,14,21,42
Greatest Common Factor
We found the factors 50,55,42 . The biggest common factor number is the GCF number.
So the greatest common factor 50,55,42 is 1.
Lets's calculate LCM of 79,66,52
2 | 79, 66, 52 |
79, 33, 26 |
∴ So the LCM of the given numbers is 2 x 79 x 33 x 26 = 135564
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 1/135564
Therefore, the GCF of Fractions 50/79,55/66,42/52 is 1/135564
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 79,66,52 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(79,66,52) = 1
common factors(in case of two or more numbers have common factors) = 2
GCF(79,66,52) x common factors =1 x 2 = 2
LCM(79,66,52) = ( 79 × 66 × 52 ) / 2
LCM(79,66,52) = 271128 / 2
LCM(79,66,52) = 135564
